CompTIA Network+ (N10-009) — Question 8

A network administrator is configuring a new switch and wants to connect two ports to the core switch to ensure redundancy. Which of the following configurations would meet this requirement?

Answer options

• A. Full duplex
• B. 802.1Q tagging
• C. Native VLAN
• D. Link aggregation

Correct answer: D

Explanation

Link aggregation allows multiple network connections to be combined into a single logical link, which provides redundancy and increased bandwidth. Full duplex, 802.1Q tagging, and Native VLAN configurations do not specifically address redundancy through multiple connections between switches.
